A mallee of the southern Australian coast from West Cape Howe to
east of Esperance in Western Australia, and also southern Eyre Peninsula
and southern Fleurieu Peninsula in South Australia but not on Kangaroo
Island. The bark is smooth but the stems often have partly shed
strips of bark hanging. The adult leaves are thick and broadly lanceolate.

Eucalyptus angulosa belongs in Eucalyptus subgenus
Symphyomyrtus section Dumaria because the buds have
two opercula, stamens are strongly inflexed, ovules are in 6 or
8 rows on the placentae and cotyledons are reniform. E. incrassata
, E. angulosa, E. captiosa , E. singularis
and E. ceratocorys are closely related within this
section Dumaria, forming series Incrassatae.

E. angulosa is a mallee of coastal headlands and dunes with
very coarse leaves, buds and fruits. E. incrassata , with
slightly smaller buds, fruits and leaves,is sub-coastal
to inland in distribution as a component of mallee communities.
The narrow-leaved and small-budded sub-coastal mallee, E. captiosa
, and coarse-leaved inland mallee with buds that are contracted
about the middle, E. ceratocorys , both have prominently
beaked opercula. The fifth species in the series is the mallet E.
singularis which has pendulous buds on slender peduncles and
pedicels and has prominently beaked opercula.

The recently described species, E. grossifolia,
from the Kamballup area of Western Australia, south of the Stirling
Range, is not recognized here as being sufficiently distinct from
E. angulosa. It differs primarily in having a more open,
erect habit which may be due to the sub-coastal habitat, compared
to the bushy habit of more coastal-growing plants of E. angulosa.

This Kamballup form of E. angulosa is locally important for
land restoration work.
